    I have a brand new Intel Core Duo 20" iMac.

    Whenever I am not using the system for a while (10+ mins) the hard drive goes to sleep (an energy saver setting). However, whenever the hard drive goes to sleep the computer makes some odd beeping sounds. They don't seem to come from the speakers, but rather from somewhere in the computer. I know it's happening when the hard drive goes to sleep because of the other normal 'hard drive sounds' and the fact that there is a lag to open finder and the hard drive makes a spin up noise after all this beeping nonsense. It also makes the beeping sometimes when coming out of standby. It is incredibly annoying.

    Is this normal? I tried a search but only found information about beeping on old G3s....

    Any help would be appreciated.

    some people have said that there has been a squeeking noise that goes away when you shut down one of the cores in the cpu, although i think your case is different you might want to try it anyway
